Water Jet CNC Stone Cutting & Milling Machine is more and more popular in the recent years since 2024. The 2 in 1 cutting and milling CNC water jet cutter machine have lots of benefits in the stones and marble products manufacturing industry. Below we would like to introduce this kinds of dedicated waterjet cutting machine for stones and marbles cutting and milling applications.
I. Technical Principles and Innovative Breakthroughs
The cutting and grinding integrated waterjet is a deep – integrated product of high – pressure water jet technology and abrasive jet technology, representing a major breakthrough in modern precision machining technology. Its core lies in the intelligent integration of an ultra – high – pressure water pump (with a pressure of up to 400 – 600 MPa) and an abrasive mixing system. A mixed jet with a speed up to three times the speed of sound is formed through an artificial sapphire or diamond nozzle with a diameter of less than 0.5 mm. After the water flow is fully mixed with abrasives such as emery in the mixing chamber, the impact energy density of the resulting multiphase flow can reach 5 kg/mm². This unique energy transfer method enables it to achieve both precise cutting of materials and surface finishing at the same time. In recent years, the iteration of direct – drive pump technology (such as the fourth – generation direct – drive system of QOMOTECH) has not only significantly improved the equipment stability but also increased the energy – efficiency ratio by more than 30% through magnetic suspension bearings and intelligent pressure compensation technology.
II. Multidimensional Technical Advantages
Material Universality
This technology can process more than 500 kinds of engineering materials, from soft chemical fiber fabrics and natural wood to high – strength titanium alloys and brittle ceramics, all of which can be processed efficiently. Notably, its cold – state processing advantages for composite materials and heat – sensitive materials (such as 7075 aluminum alloy for aerospace) are significant, completely avoiding the problems of metallographic structure changes and heat – affected zones caused by traditional thermal processing.
Process Integration
Through an innovative multi – axis linkage CNC system, multiple processes such as cutting, drilling, milling, and grooving can be completed in a single clamping, achieving a processing accuracy of ±0.1 mm. This “one – step forming” process mode not only significantly improves production efficiency but also effectively eliminates the cumulative error problems caused by traditional multi – equipment conversion.
Environmental Protection and Economy
Since it uses a pure physical processing principle, there is neither thermal deformation nor tool wear problems. The application of the closed – loop water circulation system enables the wastewater recovery rate to reach more than 90%, leading the industry. Coupled with the intelligent energy consumption management system, the overall energy consumption is reduced by more than 40% compared with laser cutting, and the comprehensive production cost can be saved by 15% – 20%.
III. Industry Application Scenarios
Aerospace: It is used for the integrated forming processing of aircraft honeycomb structural parts, perfectly solving the problem of inter – layer delamination of composite materials caused by traditional cutting methods, while ensuring the overall strength of the structural parts.
Automobile Manufacturing: It shows unique advantages in the processing of complex – curved interior parts. It can not only achieve efficient cutting but also enhance the material rigidity, significantly improving collision safety.
Precision Molds: It is applied to the micron – level finishing of graphite electrodes, and an ultra – fine surface with a surface roughness Ra ≤ 1.6μm can be obtained, meeting the needs of high – end mold manufacturing.
Hazardous Chemical Treatment: In special fields such as the disassembly of waste ammunition and the treatment of radioactive materials, its cold – cutting characteristics completely eliminate the risk of spark ignition that may occur in traditional methods.
IV. Future Development Trends
With the breakthrough applications of intelligent control systems (such as AI path optimization algorithms based on deep learning) and new abrasives (nano – emery), the cutting and grinding integrated waterjet technology is rapidly developing in three dimensions: the processing accuracy is moving towards the micron level (μ – level), the material adaptability is expanding to more complex multi – layer composite materials, and the intelligent level realizes adaptive pressure adjustment. Leading enterprises in China such as Nanjing Dadi Waterjet have led the formulation of the ISO waterjet processing international standard, promoting the large – scale application of this technology in the high – end manufacturing field. It is estimated that by 2025, the global market scale will exceed $5 billion, with an annual compound growth rate of more than 15%.
